Crocodiles

Crocodiles are considered one of the largest vertebrate animals on the planet. These frightening creatures belong to the group of reptiles , and they are the same group that includes snakes, turtles and lizards of various kinds. Crocodiles have many close relatives that can look - to the inexperienced eye - very similar to them, such as alligators (American crocodile), Gharyal (Indian crocodile) and Cayman (a very small American crocodile), but each of these animals, despite its proximity to crocodiles, has a special species independently.

Crocodile life environment

Crocodiles are aquatic animals, as they often live around fresh water bodies such as lakes, rivers or swamps, but they can also be found in salt water, thanks to the special saline glands in her body that can filter the salt from their bodies if the rate increases too much. [2] All types of crocodiles inhabit tropical regions due to their high sensitivity to cold. They are found in North Australia, Southeast Asia, all over India, and in the Americas, as well as most parts of the sub-Saharan Africa. Crocodiles are carnivores, feeding on very large game species. They can hunt fish, birds , crustaceans, and even large mammals such as buffalo, zebras and humans.


Natural adaptations to the crocodile

Crocodiles help the membranes in their legs to walk on the ground, and their eyes and noses are compatible with the conditions of life in the water until they breathe and see clearly, as her eyes have a protective film between the eye and the eyelid, helping her to see easily in the water and to provide additional protection for the eye when the eyelid is raised. Also, a characteristic of crocodile eyes is that it contains in its background a crystalline layer on which the rays of light entering the eye are reflected, which gives them a higher ability to see in dim light during the night, and in fact, most types of crocodiles depend on hunting at night instead of the day, which Take a rest. [3] Crocodiles also float a lot over the water to breathe, as well as anticipation and search for prey, and its movement is more fluid and flexible in water than many on land.

Crocodiles lay like most reptiles, and their eggs look like chicken eggs , but they are larger, less luster , and white . Crocodiles lay eggs in nests of litter and plants or in the sand on the beaches, and the female monitors and protects them - but without incubating them or sitting on top of them - until they hatch after 65 to 95 days, and when the eggs hatch the mother carries her youngsters into her mouth into the water, and she takes care of herself Feed them and train them for hunting, and you may continue to care for them for more than a year. [4]

The largest types of crocodiles

There are 14 known species of crocodiles in the world now living in five different continents , but the largest of these species is what is known as the saltwater crocodile, which is also considered the largest surviving creature from the group of reptiles, and is considered the largest predator living on land on the world. The mention of a fully developed saltwater crocodile is usually over four meters, and its weight may reach a full ton. [5] As the name of the animal suggests, it is able to live in salt water, but it often inhabits swamps, bays, delta, or low river currents. This species is considered the most widespread crocodile on the ground now, as it lives in a region that stretches from northern Australia, and across southeast Asia, to the east of the Indian subcontinent.

the biggest Crocodile in the world

It is difficult to document the largest crocodile ever found in the world, but the Jury of the Guinness Book of Records agreed to adopt a recorded claim of a giant saltwater crocodile caught in Papua New Guinea in May 1966, measuring 6.3 meters in length and weighing about 1,340 kilograms. [6] There is another record in the Guinness book of a crocodile called "Kayla" caught in the Petarkanika Park in India, where it is alleged that it reached 7 meters in length and weighed 2,000 kg. There are no documented images of any of the two crocodiles, and their measurements may not be completely accurate, as they significantly exceed any scientifically recorded numbers of other crocodiles. [7]In general, a government study conducted in Australia estimates that the largest freshwater crocodiles in the world will likely range in length from 6 to 7 meters, and their weight may be around 1,000 to 1,800 kilograms. [8]

The largest extinct crocodile

Scientists discovered in 2012 what could be the largest type of crocodile in the world in the sediments of the Turkana Basin, north of the State of Kenya, in East Africa, and is likely to prepare this alligator biggest crocodile in history to date , which he called '' Crockodelos Thorbgarnarsona " ( In English: Crocodylus thorbjarnarsoni) It is possible that the length of this crocodile reached nine meters, and thus it is considerably larger than its modern relatives such as the Nile crocodile and the saltwater crocodile. [9]

The age of this crocodile is estimated at between four million to two million years, and it belongs to the same species that includes most types of crocodiles currently on the ground, and its platoon was identified after tests conducted by geologist Christopher Brochow for a period of three years in a museum in Kenya on crocodile fossils. "The crocodile was probably able to devour human beings. The geology professor Christopher Brochow at the National Museum of Kenya in Nairobi said:" The crocodile lived with our ancestors, and it was likely that he was devouring them, "even though by doing tests they did not find Fossils of a person next to them. "We don't actually have fossil remains for humans with traces of crocodile bites, but crocodiles were larger than their counterparts today, and we were smaller, so it probably didn't require much biting," Brochow added.
